Mount Kilimanjaro stands at a whopping 19,340 feet above sea level. It’s the tallest mountain in Africa, and the highest freestanding mountain in the world. It will take the celebrity climbers an exhausting 8-day trek to reach the summit.

Each grueling moment will be captured in a TV documentary, which will record every bump, slip and trip from base camp to the summit.

The celebrity team’s incredible efforts will raise money to help change lives across Africa and the UK.

In particular, they’ll be exploring how they can help tackle malaria – a disease which kills a child every 30 seconds across Africa.

Malaria is the most widespread, potentially fatal disease present in the world today.

In Tanzania, where Kilimanjaro is situated, malaria is the leading killer of children. In a population of 38 million, there are more than 16 million cases of malaria each year, causing up to 80,000 deaths of children under 5 years of age.

By sponsoring the BT Red Nose climbers just £5, Comic Relief could provide a mosquito net to protect a mother and child from potentially fatal mosquito bites that spread malaria. Or it could go to help extremely vulnerable, poor and disadvantaged people here in the UK.
